The Aegean Cafe is tucked away behind the Royal Bank in a passage way that leads to Sussex Place. Their origin is Greek and they offer a pretty good range of light meals and salads for lunch. They also have about 4-5 different coffees which can be enjoyed downstairs or the small upstairs.
The ambiance is best described as cozy as there are only about 30 seats and it is tight. I think their lunches are a bit pricey so rarely eat there. They seem to do a booming catering business as I often see their staff delivering supplies to neighbouring offices.
The location is a bit hard to find as it's in a shaded passageway. There is nowhere to sit outside there.
